I recently received my Dygma Raise [1] after backing on Kickstarter and also beta tested their proof-of-concept tech, the "Shortcut". Their old version used a thumbstick but abandoned it after feedback; I was a little disappointed but they opted for switching the space into four separate keys which I find pretty good as an alternative.

Very glad these kinds of devices are gaining attention. At worst, a better gaming experience. At best, tackling RSI and allowing us to type/game for longer.
